Check Quilter's Cache - 12" blocks. I am working on Pinwheel #7 right now for a little boy baby. It is darling. Usiing fabric with teeny tiny little dragon flies on it and some swirly fabric in oranges, purples and deep rose colors (perfectly matches the bugs!!!!). There are a lot of ideas there.
Good luck and isn't making baby quilts a lot of fun? My next one is the Depression pattern and I am making an "I Spy" design on it for a little girl baby with puppies, and apples, and acorns and all different things - usable later to teach the child "I Spy".
